Jasper is a granular, opaque variety of chalcedony (agate also belongs to this family) which is a quartz (SiO2) mineral. However, jasper, in addition to or silica, contains an unusually large amount of impurities, mainly iron oxide. It is fine-grained and often strongly marked with orbicular or striped patterns. Red jasper is the most popular gemstone. Yellow, green, and brown colors also exist. These colors may be patchy in nature, several SiO2 of them maybe present in the same stone, and they may fade into each other. Iron combinations is the coloring agent for jasper gemstones.For instance iron oxide is responsible for the red color and oxidized ferric iron (ferrous iron) is responsible for green color. Jasper frequently show a well-developed banding. The bands may range from about one tenth of an inch to one inch in thickness. They are straight and parallel rather than concentric (opposite to banded agates). The name jasper is derived from the Greek word for spotted or speckled stone (in another source it is believed that the name jasper is derived from the ancient word iaspis). Green with red spots jasper is the traditional birthstone of March.
